How to make 18650 battery pack

  1. Measure 18650 battery cell appearance, voltage and resistance. Usually we use lithium battery automatic sorting machine, new hopper type automatic feeding structure, high-speed and stable feeding, no impact and scratches on the battery
  2. Based on battery pack solution, we probably glue the 18650 cell to fix.
  3. 18650 Automatically paste insulating highland barley paper into the hopper of automatic spot welding machine manually. Load the rolled highland barley paper into the equipment. The factory parameters have been set, just press the reset button, no need to debug any part, and then press the start button to start production.
  4. A set of three for single-row (within 10) series or parallel or multi-series and multi-parallel cells, automatic series of positive barley paper, automatic internal resistance and voltage sorting, positive and negative detection, automatic cutting of nickel sheets, and automatic spot welding. All-in-one automation equipment.
  5. Solder PCBA into 18650 cells. All components are treated as electrostatic sensitive devices.
  6. PVC insulation. Conducive to the stability of lithium battery pack performance.
  7. Final test. The main test items are: open circuit voltage, AC internal resistance, discharge test, discharge overcurrent test, short circuit protection test, charging test, charging protection test.
  8. Lebal battery pack. It shall print voltage, capacity, date, slot No, and manufacturer name.
  9. Package. Make sure that lithium batteries are individually packed in completely closed inner packaging.
